The Culture - a human/machine symbiotic society - has thrown up many great Game Players, and one of the greatest is Gurgeh: Jernau Morat Gurgeh, The Player of Games, master of every board, computer, and strategy.

The man known as Cheradenine Zakalwe was one of Special Circumstances' foremost agents, changing the destiny of planets to suit the Culture through intrigue, dirty tricks or military action.

The drone known as Skaffen-Amtiskaw knew both of these people.

The first ever collection of Iain Banks's short fiction, this volume includes the acclaimed novella, The State of the Art. This is a striking addition to the growing body of Culture lore, and adds definition and scale to the previous works by using the Earth of 1977 as contrast. The other stories in the collection range from science fiction to horror, dark-coated fantasy to morality tale. All bear the indefinable stamp of Iain Banks's staggering talent.

In the winter palace, the King's new physician has more enemies than she at first realises. But then she also has more remedies to hand than those who wish her ill can know about.

But his enemies strike more swiftly, and his means of combating them are more traditional. Spiralling round a central core of secrecy, deceit, love, and betrayal, Inversions is a spectacular work of science fiction, brilliantly told and wildly imaginative, from an author who has set genre fiction alight.

In a world renowned even within a galaxy full of wonders, a crime within a war. For one man it means a desperate flight, and a search for the one - maybe two - people who could clear his name. For his brother it means a life lived under constant threat of treachery and murder. And for their sister, even without knowing the full truth, it means returning to a place she'd thought abandoned forever.

Quoins are accepted currency throughout the thousands of worlds of the Congregation. Ancient, and of unknown origin and purpose, people have traded with them, fought for them, and stolen quoin hordes from booby-trapped caches at risk to life and limb throughout the Thirteen Occupations. Only now it's becoming clear they have another purpose...as do the bankers who've been collecting them.

Lededje Y'breq is one of the Intagliated, her marked body bearing witness to a family shame, her life belonging to a man whose lust for power is without limit. Prepared to risk everything for her freedom, her release, when it comes, is at a price, and to put things right, she will need the help of the Culture....

The Scavenger species are circling. It is, truly, provably, the End Days for the Gzilt civilization. An ancient people, organized on military principles and yet almost perversely peaceful, the Gzilt helped set up the Culture 10,000 years earlier and were very nearly one of its founding societies, deciding not to join only at the last moment. Now they've made the collective decision to follow the well-trodden path of millions of other civilizations; they are going to Sublime, elevating themselves to a new and almost infinitely more rich and complex existence.

For short-lived races like humans, space is dominated by the complicated, grandiose Mercatoria. To the Dwellers who may live billions of years, the galaxy consists of their gas-giant planets - the rest is debris.

Unfortunately, without knowing it, he's come close to an ancient secret of unimaginable importance.

But as he closes in on the secret, a killer closes in on him because the Amarantin were destroyed for a reason.

Thirteen hundred gates have opened to solar systems around the galaxy. But as humanity builds its interstellar empire in the alien ruins, the mysteries and threats grow deeper. In the dead systems where gates lead to stranger things than alien planets, Elvi Okoye begins a desperate search to discover the nature of a genocide that happened before the first human beings existed and to find weapons to fight a war against forces at the edge of the imaginable. But the price of that knowledge may be higher than she can pay. 

Sharrow was once the leader of a personality-attuned combat team in one of the sporadic little commercial wars in the civilisation based around the planet Golter.
